Segment Congruence postulate: If two segments have the same length as measured by a fair ruler, then the segments are congruent. Also, if two segments are congruent, then they have the same length as measured by a fair ruler. Congruent Segments Segment Addition postulate: If point R is between points P and Q on a line, then PR + RQ = PQ. The length of a Segment: Let A and B be points on a number line , with coordinates a and b . Then the measure of of segment AB which is called its length , is {a-b} or {b-a}. Point: exact location (named by a capital letter). Congruent Figures: Are figures that are the same size and shapes. coordiate of a point: A point on a number line that is a real number. number line: A line that has been set up to correspond with the real numbers.
